Chapter 13.5, Problem 7PPA

Interpretation Introduction

Interpretation:

Van’t Hoff factor for ${\text{MgSO}}_{\text{4}}$ at $\text{0}\text{.100 m}$ to be calculated.

Concept introduction:

Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution.  We can calculate osmotic pressure by using this formula is given by,

Osmotic pressure $\text{(π) = iMRT}$

Where,

i- Von’t Hoff’s factor

M – Molarity of the solution (mol/L)

R- Ideal gas constant (0.08206 ${\text{L atm mol}}^{\text{-1}}{\text{K}}^{\text{-1}}$)

T-Temperature in Kelvin
